Migration between 5 and 7 Gyr. First line: mass fraction of stars that migrate by more than x kpc inwards or outwards in terms of radius (solid line) or guiding radius (dashed line). Second line: mass fraction of stars that migrate outwards (right half of the plot) or inwards (left part) by more than x kpc in terms of radius (solid) or guiding radius (dashed). The yellow lines in these two plots are the corresponding migration from 1 to 3 Gyr (identical to the curves of Fig. 9). Third and fourth lines: same study, but only for stars with a radius (solid lines) or a guiding radius (dashed lines) around R_i.
